L.T.ITO™ (Low Temperature I.T.O™)

Thin Film Devices utilizes Ion-Beam Sputter, where deposition is performed at temperatures as low as 30°C – 60°C.  The Low Temperature ITO™ Sputtering process minimizes the temperature buildup on the part during deposition. And yet it continues to exhibit very good adhesion, durability and transmittance. The Low Temperature ITO™ Coatings are typically deposited on a variety of Plastics, Acrylics, Polycarbonate, Crystals, LCD Color Filters, PET and Polymers.  The resistivity’s of 10 to 500 ohms/sq. are routinely achieved.

TFD typically recommends that all plastics be hard Si-Coated, by Spray or Dip Methods, prior to any coating, to reduce the material’s internal out-gassing chemical and mechanical changes.

This Low Temperature I.T.O.™process allows I.T.O. to be deposited on finished products such as Touch Panels, Polarizer’s, Privacy Screens and other finished products for E.M.I. Shields, Heaters, and other display applications.

Specifications:

TFD’s unique sputtering process, IBS where deposition is performed at temperatures as low as 30 °C – 60 °C. The LTITO™ exhibits good adhesion, durability and transmittance. The LTITO™ process coatings are deposited on a variety of acrylics, crystals, LCD color filters, Polycarbonate, PET & polymers.

The LTITO™ sputtering process is unusual as it minimizes the temperature buildup on the part. Resistivities of 10 to 500 ohms/sq are routinely achieved.

Generally, all plastics are Si-hard coated by spray or dip methods prior to any coating. The Si-hard coat provides a higher level of adhesion and mechanical durability.
